Granular-bed filtration assisted by Filter-cake formation: 4. Advanced designs for Panel-bed filtration and gas treating
Powder Technology, 2005Co-Authors: A.m. SquiresAbstract:Abstract “Historic” Panel bed Filter louvers slope upward toward their outer edges. Improved louver designs exploit the discovery that puffback renewal of gas-entry sand faces is more effective if louvers slope downward toward outer edges. For given Panel bed height, down-sloping louvers present larger total gas-entry sand face, affording equipment that occupies smaller ground area for given Filtering capacity. As well, for down-sloping louver designs, other means can create a gas-entry-face renewing body movement, viz., a sharp motion (either, as appropriate, sideways, downward, or upward) such as may be effected by the blow of a hammer. Newly conceived arrangements of flat-plate louvers are particularly attractive relative to historic louvers: resembling subway gratings, they cost less, and are better suited for use in a Panel bed that provides for countercurrent contacting of gas and powder. Also reported is a new “Panel Filter” comprising downwardly sloping “Filter trays” mounted one above another, each tray displaying a gas-entry-face renewable either by puffback or hammer blow. For Filtering a given flow of gas, a Panel of Filter trays can occupy smaller ground area than louvered beds, can be assembled from fewer elements, and can afford a lower pressure drop.

2016Co-Authors: Tadeusz DziubakAbstract:Common impurities found in the inlet air to the internal combustion engine of motor vehicles are characterized. Dust concentrations in the air were analysed for different operating conditions of a motor vehicle. It is shown that the most common and the most harmful air impurity for the technical machinery is a mineral dust from roads. The benefits of using the inertial Filter (multicyclone) as a first stage of air filtration, including extended engine life are presented. The methods of dust extraction from a dust collector of the air Filter multi-cyclone are shown. The necessity of regular ejection dust extraction from the multi-cyclone dust collector is shown. A dust extraction rate m0 is defined and its effects on the cyclone separation efficiency and flow resistance are shown. The test method and the test conditions for a two-stage Filter in multi-cyclone - non-woven fabric Filter element configuration are developed. The characteristics of the separation efficiency and flow resistance of the cyclone and the non-woven fabric Filter were determined as a function of dust mass supplied with the inlet air to the two-stage Filter for three different extraction rates and without dust extraction from the multi-cyclone dust collector. The separation efficiency and flow resistance were determined for a multi-cyclone and a non-woven fabric Filter without dust extraction from the multi-cyclone dust collector and with or without periodical maintenance. The benefits of periodical cleaning of the dust collector were shown.

Technological Innovation of the Hot Air Circulation System Filtration Device in Super Resurgence Machine
Mechanical Engineer, 2013Co-Authors: Yuan Guo-yongAbstract:The Super resurgence machine is one of the key equipment of the cigarette companies processing workshop,which is used to increase the tobacco silk moisture and temperature to meet the technological requirements of the bake-wire device expansion function.The hot air circulation Filters wind system of the super resurgence machine at the exit of the tobacco affects silk moisture infrared cytometry data accuracy greatly,and the flat Panel Filter stagnant water can form a wet mass smoke.The flatbed Filter technology is substituted by the rotatonal strainer.

Pilot study of high‐performance air filtration for classroom applications
Indoor Air, 2012Co-Authors: Andrea Polidori, P. M. Fine, V. White, P. S. KwonAbstract:A study was conducted to investigate the e! ectiveness of three air purification systems in reducing the exposure of children to air contaminants inside nine classrooms of three Southern California schools. Continuous and integrated measurements were conducted to monitor the indoor and outdoor concentrations of ultrafine particles (UFPs), fine and coarse particulate matter (PM2.5 and PM10, respectively), black carbon (BC), and volatile organic compounds. An heating, ventilating, and air conditioning (HVAC)-based high- performance Panel Filter (HP-PF), a register-based air purifier (RS), and a stand-alone air cleaning system (SA) were tested alone and in di! erent combinations for their ability to remove the monitored pollutants. The combination of a RS and a HP-PF was the most e! ective solution for lowering the indoor concentrations of BC, UFPs, and PM2.5, with study average reductions between 87% and 96%. When using the HP-PF alone, reductions close to 90% were also achieved. In all cases, air quality conditions were improved substantially with respect to the corresponding baseline (preexisting) conditions. Data on the performance of the gas-absorbing media included in the RS and SA unit were inconclusive, and their e! ectiveness, lifetime, costs, and benefits must be further assessed before conclusions and recommendations can be made.
